Quantum dots (QDs), such as cadmium selenide (CdSe) and lead selenide (PbSe) exhibit excellent optical, magnetic and chemical properties due to their extremely size (ca. 1–10 nm) and are attractive semiconductor nanomaterials for optical studies and energy storage. In this study, aqueous synthesis of CdSe and PbSe QDs in a size range of 2–10 nm was described. Synthesized QDs were characterized using SEM and TEM, DLS, zeta potential, FTIR, EDX and XRD. Highest accumulation (72.5 ± 5.8 mg L⁻¹) of PbSe QDs occurred at 10 ppm suspensions. In general accumulation increased up to 48 h exposure then fluctuate tended to decline. For CdSe QDs, accumulation tended to decrease for 72 h exposure except that for 5 ppm groups. For the elimination period, in general, the elimination levels of PbSe and CdSe QDs from exposed individuals decreased (p < 0.05) even it has some fluctuate.

量子点（QDs），例如硒化镉（CdSe）和硒化铅（PbSe）由于其极小的尺寸（约1–10 nm）而具有出色的光学，磁性和化学性质，是用于光学研究和能源的有吸引力的半导体纳米材料存储。在这项研究中，描述了CdSe和PbSe QD的水合成，尺寸范围为2-10 nm。使用SEM和TEM，DLS，ζ电位，FTIR，EDX和XRD对合成的量子点进行表征。最高积累（72.5±5.8 mg L ^-1的PbSe QD在10 ppm悬浮液下发生。一般而言，在暴露至48小时后，积累量增加，然后波动趋于下降。对于CdSe量子点，在暴露5 h的情况下，累积积累倾向于减少72 h，而5 ppm组除外。对于消除期，一般来说， 即使暴露水平有所波动，暴露个体的PbSe和CdSe QD消除水平也会降低（p <0.05）。
